(Main)Radiation protection instrumentation - Alarming personal radiation devices (PRDs) for the detection of illicit trafficking of radioactive material
Radiation protection instrumentation - Alarming personal radiation devices (PRDs) for the detection of illicit trafficking of radioactive material
IEC 62401:2017 describes design and functional criteria along with testing methods for evaluating the performance of Personal Radiation Devices (PRDs) used for detection of illicit trafficking of radioactive material (e. g., for border radiation monitoring). This document applies to alarming radiation detection instruments that are pocket-sized, carried on the body and used to detect and indicate the presence and general magnitude of gamma radiation fields. Neutron detection may also be provided.
This new edition includes the following significant technical changes with respect to the previous edition:
a) making the standard consistent with the new standards for detection of illicit trafficking of radioactive material (see the Introduction);
b) changing some basic requirements;
c) creating a uniform functionality test for all environmental, electromagnetic and mechanical tests;
d) reference to IEC 62706 for the environmental, electromagnetic and mechanical test conditions.
Instrumentation pour la radioprotection - Dispositifs individuels d'alarme aux rayonnements pour la détection du trafic illicite des matières radioactives
IEC 62401:2017 décrire les critères fonctionnels et de conception ainsi que des méthodes d'essai pour évaluer les performances des PRD utilisés pour la détection de trafic illicite de matières radioactives (par exemple à la surveillance des frontières). Le présent document s'applique aux instruments de détection de rayonnement avec alarme qui sont portables en poche ou sur l'individu et qui sont utilisés pour détecter et signaler la présence et l'ordre de grandeur des champs de rayonnement gamma. La détection neutronique peut également être fournie.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) cohérence de la norme avec les nouvelles normes relatives à la détection du trafic illicite de matière radioactive (voir Introduction);
b) modification de certaines exigences:
c) création d'un essai de fonctionnalité uniforme pour tous les essais environnementaux, électromagnétiques et mécaniques, et d'une exigence relative au coefficient de variation de chaque relevé de moyenne nominal;
d) référence à l'IEC 62706 pour les conditions d'essais environnementaux, électromagnétiques et mécaniques.
